Following intravenous administration of physostigmine salicylate for tricyclic antidepressant poisoning in 21 patients, convulsions occurred in two patients, and severe cholinergic manifestations occurred in two others. Because of these untoward effects and the very short duration of its beneficial
Maprotiline, a new tetracyclic antidepressant, has a pattern of toxicity that is different from that of tricyclics. Maprotiline overdosage appears more likely to cause seizures but less likely to cause the peripheral autonomic and cardiac manifestations seen with tricyclics. Two cases of maprotiline
Tricyclic antidepressants are among the commonest causes of both non-fatal and fatal drug poisoning in the world. Their toxicity is due to effects on the brain, the heart, the respiratory system and the parasympathetic nervous system. Symptoms usually appear within 4 hours of an overdose and all but
Protection efficacy of continuous prophylactic administration of physostigmine and scopolamine against sarin-induced toxicity was evaluated previously in guinea pigs. The present study in large animals used Beagle dogs, that serve as an animal model with cholinergic sensitivity similar to that of
Visual observations were made to compare the pretreatment benefits of subacute (75 micrograms/hr, sc) and acute (146 micrograms/kg, im, at 30 min) deliveries of physostigmine salicylate (Phy) against 2 or 5 LD50s (60 or 150 micrograms/kg, sc) of soman in guinea pigs; scopolamine, 80 micrograms/kg,
Seventy-three jimsonweed exposures reported to a regional poison center over a five-year period were reviewed. The ingestors' mean age was 17.3 years (range, 11 to 28 years). The most common route of exposure was oral, and the circumstance was drug abuse or experimentation in the majority of the
Physostigmine salicylate, a cholinesterase inhibitor, has been shown to reverse the effects of certain drugs with anticholinergic properties. The paper provides a brief historical account of physostigmine, reviews the cholinergic drugs and their effects and suggests a management protocol based on
